Abstract

: Pollen morphology of 34 taxa belonging to genera Scabiosa and Lomelosia were investigated using a light microscope (LM) and scanning electron microscopy (SEM). Pollen grains of Scabiosa and Lomelosia taxa are tricolpate and triporate, respectively. Pollen shapes vary from oblate to prolate. The exine surface ornamentation can be divided into five types, namely echinate, echinate-microechinate, echinate-gemmate, echinate-microechinate/gemmate and microechinate-gemmate. Pollen grain sizes were classified as very large in three species of Lomelosia and large in the rest. Statistical analyses revealed some quantitative morphological features, such as equatorial axes, L (polar view amb), and t (apocolpium) as the primary characters for separating the examined taxa. The taxa were separated from each other by clustering analysis of selected pollen characters, and the investigated species were placed within two clusters. Present findings revealed that some Scabiosa species should be transferred to Lomelosia depending on palynological characters.

土耳其 Scabiosa L. 和 Lomelosia Raf.（木贼科）分类群的花粉形态学

:使用光学显微镜（LM）和扫描电子显微镜（SEM）研究了莨菪属（Scabiosa）和Lomelosia属（Lomelosia）34个分类群的花粉形态。Scabiosa 和 Lomelosia 类群的花粉粒分别为三梭形和三梭形。花粉形状从扁球形到长球形不等。花粉表面的纹饰可分为五种类型，即棘刺、棘刺-微棘刺、棘刺-盖玻片、棘刺-微棘刺/盖玻片和微棘刺-盖玻片。有 3 种 Lomelosia 的花粉粒尺寸被归类为超大，其余的则被归类为大。统计分析显示，一些定量形态特征，如赤道轴、L（极视角amb）和 t（顶端apocolpium），是区分所研究类群的主要特征。通过对选定的花粉特征进行聚类分析，将分类群彼此分开，并将所研究的物种归入两个群中。目前的研究结果表明，根据古植物学特征，一些 Scabiosa 种类应归入 Lomelosia。

期刊介绍： The Turkish Journal of Botany is published electronically 6 times a year by the Scientific and Technological Research Council of Turkey (TÜBİTAK) and accepts manuscripts (in English) covering all areas of plant biology (including genetics, evolution, systematics, structure, function, development, diversity, conservation biology, biogeography, paleobotany, ontogeny, functional morphology, ecology, reproductive biology, and pollination biology), all levels of organisation (molecular to ecosystem), and all plant groups and allied organisms (algae, fungi, and lichens). Authors are required to frame their research questions and discuss their results in terms of major questions in plant biology. In general, papers that are too narrowly focused, purely descriptive, or broad surveys, or that contain only preliminary data or natural history, will not be considered (*). The following types of article will be considered: 1. Research articles: Original research in various fields of botany will be evaluated as research articles. 2. Research notes: These include articles such as preliminary notes on a study or manuscripts on the morphological, anatomical, cytological, physiological, biochemical, and other properties of plant, algae, lichen and fungi species. 3. Reviews: Reviews of recent developments, improvements, discoveries, and ideas in various fields of botany. 4. Letters to the editor: These include opinions, comments relating to the publishing policy of the Turkish Journal of Botany, news, and suggestions. Letters should not exceed one journal page. (*) 1. Raw floristic lists (of algae, lichens, fungi, or plants), species descriptions, chorological studies, and plant sociology studies without any additional independent approaches. 2. Comparative morphology and anatomy studies (that do not cover a family, tribe, subtribe, genus, subgenus, section, subsection, or species complexes with taxonomical problems) without one or more independent additional approaches such as phylogenetical, micromorphological, chromosomal and anatomical analyses. 3. Revisions of family, tribe, genus, subgenus, section, subsection, or species complexes without any original outputs such as taxonomical status changes, IUCN categories, and phenological and ecological analyses. 4. New taxa of all plants without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group. New records of all plants without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group may be accepted for peer review if they contain 3 or more new records or taxonomical status update, such as lectotypification, new combinations, transfers, revivals and synonyms. 5. New taxa of algae, lichens, and fungi without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group. New records of algae, lichens, and fungi without any additional independent approaches such as phylogenetical, ecological, chromosomal, chorological and correlational analyses in addition to a detailed macro- and micro-morphological descriptions with quality field and microscopic illustrations of taxonomically important structures and identification key in the taxonomic group may be accepted for peer review if they contain 5 or more new records or taxonomical status update, such as lectotypification, new combinations, transfers, revivals and synonyms.
